During those days that I was sick, I had a colleague who developed brain cancer. We were on a night shift engineering work and it's hard to sleep during daytime.

Cancer is not only brought about by inherited genes, but also things that we intake in our body and processes that disrupts our normal body processes.

A good example as what I mentioned is the consistent and long term lack of sleep can lead to brain cancer and this is supported in science.

Another thing is physical exercises. People think that exercise is healthy, indeed it is in aspects of say strengthening muscle groups including the heart, making strong the lungs and bone density, and others. But people forget or they are unaware that exercise also generates free radicals in the body and these free radicals can impart mutation leading to a cancer of some sort.

Even in the SOF community where operators are physically fit because of massive amounts of workouts, they do share a percentage of individuals who developed cancer.

Too much of everything kills 🤣
